fix: Add ARM64 cross-compilation support for CGO builds

- Install gcc-aarch64-linux-gnu for Linux ARM64 builds in CI
- Set CC=aarch64-linux-gnu-gcc for cross-compilation
- Make local ARM64 builds conditional on cross-compiler availability
- Provides helpful message when cross-compiler is missing locally

This fixes build failures when cross-compiling ARM64 binaries with
CGO enabled for SQLite support.
